That’s the thing about playing a gig in New York: You never know who’s going to show up. When Glen Hansard was doing a taping for Sirius/XM’s “The Loft” at The Living Room, that special guest was fellow Irishman Bono. The U2 frontman took the stage, trading verses with Hansard on “The Auld Triangle”—a modern Irish anthem written in the early ’60s by Dominic Behan for the play The Quare Fellow.

Hansard’s solo debut Rhythm and Repose will be released June 19 by Anti- Records. He begins a short U.S. tour June 12 in New York.
